Amy Rose is a Pink Hedgehog who is the embodiment of cute things and raw willpower. She was saved by Sonic when she was little and became obsessed with him ever since. While they have a good friendship, her love is always rejected by Sonic, mostly due to her age. She was once as old as Tails, however a wish made upon the Chaos Emeralds allowed her to skip 4 years of her life to be a little more maturer physically. Mentally, while strong willed and independent, she's still very immature and will let her anger get the better of her, but her love for Sonic has pushed her to do incredible things, such as physically train herself to the point where she can keep up with him while running.

The voice I am looking for a voice similar to her 4Kids actor, Lisa Ortiz, here is an example of her voice work. (NOTE: You are auditioning for both Modern AND Classic Amy):
